RHR Won't Power up after loss of power

[OggyOggy]

2012 Ram 2500 - I was out of town for about 6 weeks and when I returned the batteries were dead. Recharged them and everything appears ok but the RHR radio thing doesn't work, black screen. If I push Open/close it shows me the Dodge Uconnect screen but then goes black again.

Any ideas?

Thanks,
Joel

Good chance they are bad. Disconnect ground cables for a while then see what happens. May need to load test them.

Find the fuse, it should be taped to the harness near the AC and heater lines under the hood. If not it is taped to the harness near the brake booster. Pull the fuse for a couple minutes, then start the truck a couple times waiting for everything to go to sleep for about 10 minutes between starts. Pull the key out and open and shut the door for it to go to sleep. Make sure nothing is plugged into the DLC also.

Took apart the center to remove the radio. Bumped a button and it worked. Weird...
